网络编程是做什么的网站优化课程

1.application.properties配置
spring.data.mongodb.database=[数据库名]
spring.data.mongodb.host=localhost[主机名,本机：localhost]
spring.data.mongodb.port=[数据库端口，默认:27017]2.根据数据库文档定义实体类：
@RequiredArgsConstructor
@ToString
@Document(collection = "first")
@Setter
public class UserData {@MongoIdObjectId id;@NonNullprivate Integer code;@NonNullprivate String name;@Field("data")private Data data;private String message;@Field("refresh_token")private String refreshToken;private String status;private Integer ttl;
}
@Persistent
@Collation
@Inherited
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.TYPE})
public @interface Document {@AliasFor("collection")String value() default ""; // 指定文档名@AliasFor("value")String collection() default ""; // 指定文档名String language() default ""; // 指定文档语言@AliasFor(annotation = Collation.class,attribute = "value")String collation() default ""; // 指定排序规则
}3.声明接口，可在接口定义自定义查询方法：
public interface FirstRepository extends MongoRepository<UserData, String> {}4.注入依赖，可使用自带的插入等方法
@Repository
public class Example {private final FirstRepository firstRepository;@Autowiredpublic Example(FirstRepository firstRepository) {this.firstRepository = firstRepository;}public void insert(UserData userData) {firstRepository.save(userData);System.out.println("插入完成！");}
}5.运行实例即可
@SpringBootApplication
public class DemoApplication {public static void main(String[] args) {ConfigurableApplicationContext context = SpringApplication.run(DemoApplication.class, args);UserData userData = new UserData(200, "xzt");Data data = new Data(400);userData.setData(data);Example example = context.getBean(Example.class);example.insert(userData);}}
